It is believed that cheek dimple genes occur on the 16th chromosome, whereas cleft chin genes occur on the 5th. 23andMe research studies show that at least nine different genetic variants contribute to dimpling. The inheritance patterns of single gene diseases are often referred to as Mendelian since Gregor Mendel first observed the different patterns of gene segregation for selected traits in garden peas and was able to determine probabilities of recurrence of a trait for subsequent generations. Now, researchers know this cherubic trait is more complex than people originally thought. The basic laws of inheritance are important in understanding patterns of disease transmission. People used to think dimples came from a single, dominant gene inherited from a parent. However, not all genetic conditions will follow these patterns, and other rare forms of inheritance such as mitochondrial inheritance exist. Of course, if neither parent has dimples and they do not carry any genes for them, the baby will not either.Д¬onsidering this, are dimples inherited from the father? Several basic modes of inheritance exist for single-gene disorders: autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. If you or your partner has dimples, there is a 50% chance your baby will have them. Early geneticists reported that curly hair was dominant and straight hair was recessive.ДЄlso Know, can two parents without dimples have a child with dimples? Since dimples are a dominant trait, only one parent needs to have them. This trait is reportedly due to a single gene the presence of freckles is dominant, the absence of freckles is recessive1. However, other scientists have reported that the interaction of two genes is responsible for this trait. Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples.ДЄccordingly, are freckles dominant or recessive traits? Dimples-indentations on the cheeks-tend to occur in families, and this trait is assumed to be inherited.
